Will a longhorn bull put horns on an angus?
No. Horns are recessive-dominant, thus only appear if both parents are heterozygous polled (appear polled but have the horn gene), one is horned and the other hetero polled, or both are horned. Angus are homozygous polled, which means the first generation of offspring from a cross such as this will give you calves that are polled. They will, however, have the horn gene which means that if they are bred to a horned bull or cow, there's a much greater chance that their offspring will be horned.
If you mate a Hereford bull with horns to a female without horns if the female is homozygous for the no horns how many calves could be born without horns Why?
This is not a matter of how many it's a matter of chance in terms of percentages. In this example, any bull that is horned is ONLY homozygous, both phenotypically AND genotypically, for horned because the horned gene in cattle is recessive. The polled (non-horned) characteristic in cattle is a dominant trait both phenotypically and genotypically. So that means that any horned parent that breeds a homozygous polled parent will have offspring that are ALL polled. The only way you will get horned offspring is one of two ways: a horned sire mates with a horned dam, or, a hetero polled sire mates with a hetero polled dam (resulting in a much smaller chance than the first way). The question above is answered as followed:Homozygous Horned (Hereford) bull x Homozygous Polled female = 100% Polled offspring.I cannot use the Punnett square on this site, but if you use it on a piece of paper you will see that 100% of all offspring are polled. But notice that genotypically they are HETEROZYGOUSLY polled. This means they are polled physically, but in their genes their offspring have a 50% chance, should this offspring be bred to a horned partner, of having either horned offspring or polled offspring. If the offspring of the above cross were bred to a polled partner, the results would be 50% hetero polled and 50% homozygously polled. AND, if the above offspring were bred also to a hetero polled partner, you would get, phenotypically, 75% polled and 25% horned. Genotypically, this is 25% homozygously polled, 50% hetero polled, and 25% homozygously horned.See, the most a cow can have in her lifetime is 20 calves. There is no way that she can have 100 or so calves in her lifetime to see this example work out. Producers have to go by chances of an event happening when selectively breeding cattle, not how many.
What does polled mean for a sheep?
Polled cattle are those that are born without any buds that grow into horns. Instead they have in the middle of the top of their heads a knobby area that is called a poll, thus the reason that hornless cattle are called "polled." Polled is a genetic trait that is used in a lot of cattle today, and is a trait to be taken advantage of when the offspring has a horned sire or dam.
Do all bulls have horns?
No, not all bulls have horns. Some breeds are naturally polled (hornless) or have their horns removed at a young age for safety reasons. Horns can vary in size, shape, and texture depending on the breed of the bull.
How big is a bulls horns?
Bull horns can vary in size depending on the species and age of the bull, but they typically range from 18 inches to 30 inches in length, with a circumference of around 8 to 12 inches. The horns can be curved or straight, depending on the breed of bull.
What has a polled bull had cut off?
A polled bull (or cow) is an animal that was bred to not develop horns. However, a bull that developed horns but then had them cut off (called dehorning) may also be mistakenly referred to as a polled bull.

What breed of female cattle have horns?
Almost all breeds of cattle are born with buds, the ability to grow horns. The horns are almost always removed at a young age. Sometimes farmers allow the cattle to grow horns, depending on what breed they're raising. A few breeds have been developed in which the offspring are polled, that is, do not have the ability to grow horns. Holsteins are naturally horned, so their horns need to be trimmed or cut before their horns get too big, which is when they are a few months old if horn buds can be seen or felt. However, other cows can be born polled or hornless and do not need to have their horns trimmed. Horns is a recessive gene in cattle, so if a horned cow mates with a polled bull, the offspring will be polled. But mating horned with horned produces horned offspring, or hetero polled with hetero polled have a 25% chance of producing horned offspring. The naturally polled breeds of cattle include Angus, Red Angus, Brangus, Red Brangus and Galloway.

Are an Angus bull's horns hollow?
Angus bulls don't have horns. The Angus breed itself is naturally polled. A bull that is born from a registered Angus cow and registered Angus bull and comes up horned or scurred is not qualified to be a registered purebred animal, no matter what Angus association it is. And no bovine's horns are hollow. You can see that from the horns that are tipped on rodeo bulls or some range cows.
What are bulls with horns called?
A horned cow. That's it: End of Story. A "cow" or cow with horns is NEVER nor should EVER be called a bull. Bulls are just as capable of having nor horns as cows are capable of having horns. To say that a bovine has horns makes it a bull is indicative of a person very misinformed and ignorant of bovine genetics and physiology.
Do cows have long horns or bulls?
No. Also, there is no such thing as a "bull cow." It's either a bull (an intact male bovine used for breeding) or a cow (a mature female bovine that has had at least two calves), but never a "bull cow."
In cattle the hornless condition (H) is dominant and the horned condition (h) is recessive. A bull without horns is crossed with a cow with horns. Of the four offspring one (1) is horned and three (3)?
In this scenario, the bull without horns has the genotype HH or Hh, while the cow with horns must have the genotype hh since horned is recessive. Since one offspring is horned (hh), the bull must be heterozygous (Hh) to produce this result. Therefore, the offspring genotypes are one horned (hh) and three without horns (Hh), reflecting the dominant trait of hornlessness in the bull.
